1'0 atl wiz/0m, itvtcvy concern: Be it known that I, ALBERT GLOOR, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful De? vice for Applying Paste to Cores, of which the following is a specification.

My invention comprises a device or mechanism for applying paste to the members of sectional cores, which pasting has heretofore been done by hand 5 and the object of my inmechanism capable of doing the work' heretofore done by hand, as ljust stated, but also to provide a device or mechanism capable of better results than the hand method and of more rapid work.

The various features of advantage and utility of my device will be apparent from the description hereinafter given.

In the drawings, Figure l is a plan view of my machine; Fig. 2, a side elevation thereof with a portion broken away to expose parts within the tank or receptacle which holds the paste, Fig. 3, a section, partly in elevation, of a modiiied form of construction; and Fig. 4, a bottom plan view of the construction of Fig. 3.

Referring to the present embodiment of my device or mechanism as herein shown, the same comprises a tank or receptacle l, which may be varied as to size and dimensions, according to the size of the patterns to be operated upon or according to desire. This tank, which may be made of any suitable material, is arranged to contain the paste usually employed for pasting sectional cores together.

My invention in its broadest aspect con# sists in providing a tank or receptacle as above described and providing also means whereby the core and the surface of the paste may be brought into contact by either moving the core relatively to the surface of the paste or so moving or raising the surface of t-he paste to contact the core. rFhe first method described is illustrated in Figs. land 2, the former method being the preferable one.

Referring to the construction of Figs. l and 2, I provide a supporting-plate 2 of such dimensions as to iit within the tank and to be suitably guided at the ends thereof, as .by means of a series of vertical pins 3, which l form a bearing for the ends of this supportingplate and kee the same from contact with the ends of t Ie tank. This plate is arranged to receive and support the core, and in orderthat the same may move vertically in exactly a horizontal position I place or mount this plate upon a frame which is capa'- ble of imparting or permitting to be imparted thc desired movement to the support-v ing-plate 2, with the result that when the plate, with its core thereon, is depressed the under side of the plate will contact the surface of the paste uniformly and evenly over the entire surface. This frame consists in the present instance of a series of rock-arms 4 and a )air of rock-shafts 5 near opposite ends of the tank, there being two rock-arms connected with each rock-shaft. Also in the present instance these rock-arms are so positioned as to support the four corners of the plate and are, moreover, adapted to support the same and hold it elevated, as shown in Fig. 2 with a yielding pressure, as by means of counterweights hereinafter4 described. To between the' supporting-plate and the series of rock-arms, these rockearms are each made in the form `of a yoke', as seen in Fig. l, in whose outer ends is journaled a grooved roller 6, which is adapted to receive in such groove adepending guide 7, there being, of course, inthe present instance 'four of these rolling connections between the supportingplate and its movable frame, as clearly indicated in Fig. 1. In order to compel all of the rock-arms to move in unison, and thereby preserve the horizontal position of the supporting-plate at all elevations, I provide suitable connections between the rock-shafts 5, which in the present instance comprises two pairs of intermeshing quadrants S, secured at the outerends of the rock-shafts 5, which, as shown in Fig. 1, are projected through the sides 'of the tank. For the purp'ose of not only counterbalancing the supporting-frame, but also holding the same in elevated position with a yielding pressure, I increase the weight of the quadrants at their outer end or provide the same with regular eounterbalancing-weights 9, which may be of such increased'weight as to hold the supporting-plate in its upper position for the purposes already explained. In order to provide for the passage of the provide for the necessary rolling action IOO paste through the plate when the latter is forced downwardly and to thereby apply the paste to the core, I provide the plate with a series of openings or slots which are of a character and of an arrangement which is varied according to the particular core being operated upon. In the present instance I have for the sake of a clear description of rny invention illustrated a form of plate which is adapted to the pasting of cores employed in the molding of cast-iron sections of boilers, such as the ordinary house-heating boiler, it being understood that the supporting-plate 2 is simply loosely or removably Imounted upon its supporting-frame and that such plate may be removed and another plate substituted according to the particular character of core to be operated upon. In the particular instance now being described the plate is provided with a series of slots or openings 10, which are so formed or disposed as to give the greatest amount of opening permissible for the particular core to which this plate is adapted, so as to apply the paste uniformly over the meeting surfaces of the core. By preference the plate is provided with strengthening-ribs 11 which also serve to support the portions 12 of the plate between the slots or openings.. The plate is also rovided with an opening 13, through whic additional paste maybe supplied and which may be covered by a suitable lid or other closure, as may be desired. Furthermore, each plate may be Vprovided with guides 14, inclined inwardly and downwardly, so as to properly position the core upon the plate.

In practice the core is placed flat upon the supporting-plate withthe side or surface to be pasted resting upon such plate. The weight of the core of such weight increased by pressure of the hand causes the depression of the plate suflicient to bring the plate into contact with the surface of the paste, Whereupon such paste is forced through the openings and upon the surface of the core. In

other words, the paste is stenciled upon the core. The core will now be found to be supplied with paste uniformly and evenly over its surface, which is to be pasted onto its companion section, and the operation is repeated, with the result that the work is not only done with greater facility, but with betterresults as compared with the old and well-known hand method of applying the paste. Instead of permitting the Weight of the core or the pressure of the hand of the operator to depressv the supporting-plate it is possible to operate the plate by simply rocking the rock-shafts 5 by hand, either by manipulating the quadrants or providing an operating-handle upon one of the rock-shafts, which may be done in an obvious manner. Moreover, although I have described my invention as capable of applying paste to a single core at one time it is obvious that the plate may be adapted to apply paste to a plu-v laced thereon in rality of separate cores ess size than the case such cores were of plate. A

Referring neXt to the modied form of construction illustrated in Figs. 3 and 4, the supporting-plate 2 for the core instead of being made movable and thereby being brought into contact with the'surface of the paste, is made stationary and the reverse method adoptedthat is to say, the paste is the movable element and is itselfbrought into contact with the supporting-plate- To accomplish this result, I provide .the tank 1 with a supple mentary chamber 1a in the bottom thereof, which latter chamber is in the form of a piston-chamber tolreceive a piston 15. This piston is normallypositioned at the bottom of the piston-chamber with the body of the paste filling such chamber; but when such piston is elevatedin the manner hereinafter explained the paste in such chamber is discharged into the tank proper, and the level of paste thereby raised in the latter. For operating the piston the same'is provided with a piston-rod 16, depending through the bottom of the piston-chamber in position to be contacted and operated by the crank-arm 17, secured to the rock-shaft 18, which shaft is adapted to be rocked by hand through the medium of the operating-handle 19, all as clearly indicated in Figs. 3 and 4.

In practice the core is laid upon the supporting-plate, which is here stationary, and the handle 19 is drawn to the left, Fig. 3, and the level of the paste thereby raised and the same brought into contact with the core through the openings in the plate.
